To all whom it may concern:

Be it lillO'Wll that I, QBLRISTEN J. Poms-- son, 2. citizen of the United States, To icing ct Chicago, in the county of Cook and State of Illinois, have invented. certein x ew and useful Improvements in Filing-Machines, of which the following is e specification.

This invention relates more particularly to fi ng machines of the size and. chsrectet" to he used on a were bench; and. 1 he present invention is to so construct machine that it will be soilicieiitly compact in form to adapt it for bench usage and at the same time suiii cieiitly 011;; and. rigid to Withstand the aid. usage.

object of the invention is to: so H d en's-11 e the for the that tiioiilc can be essilv fill" h ally clamped regardless oi the taper or igumtioi'l oi the tang.

The have 21 further relates to the means employed 91 adjusting mid holding the upper end of the file; to the mechanism for reciprocating the file blade,- snd to the ch'itch mechanism for regulating the power ti'ensniission.

T he invention further consists in the fee.- tures of construction and combination of parts hereineiei described and claimed.

the tire. ings, T 'gui'c l is a side elevec entice machine; 2 alongituliinal sec ionel elevation of the same; Fig. 3 a front elevation; Fig. l en enlarged sec-- tionsi detail of the file tang socket and reciprocating; mechanism; Fig. 5 e cross sec tionsi view of the Vertical guideways; end Fig. 6 on edge elevation of the slotted driving Wheel. The machine comprises a bed plate 7, attested to he sccui'ecl to the top of a bench sln'iiler structure, which. bed plate is pro" titled, at its forward end, i

- an upright framework 8, eompiisieg vertical posts 9, ,fiiOVldml ct their lower ends with feet 10, which are secured to the bed plat-c by means of bolts 1.1 or in any other suitable manner. The posts etc beveled on their inner edges 12, and each ofthe posts has secured to its inner face e vertically cxteiidiiig her 13,

which overlies thebeveled inner edge oi? the post ehdw forms, in combination therewith,-

e f shepecl guidewey. Eetween the tWo guuiewcys thus formeo is mounted a recipguide mile 16 seal thereon at reas ess May locating frame it, which com r-isee vei.""":- siile iciis 1.5 the eii gesoi which are he to ccnfoi'm to the bevel oi the guslewevs within which they" travel. The side mils are connected by lower end; upper stress 17, respectively, and 50 above the uppercross guide-mil top socket rail 18 which, inits center, is pro vided with s recess 19, for the iecegition of the enci 0: the file The socket Efill. is

reinfozrceal s1 l sizpgcrted adjacent to the recess 19 by em; of vertical posts 2G, itpwerdly eigtc mg t me the upset cross geitle rail. The Whole, heme thiis formed is adapted to reciprocate all? I oils. {lows tween the cortical posts end serves to re W cipzocste the file ceriiesi thereby. The

socket rail 18 has asst or etherwise-ioiimeii' ctengsler socket bloc which reefw oily elite-lids the i the socket rail end ispiovirled, iii. its fees, with s rectcugcler recess 3311,; of which recess is e' pleteiZS, whichis eecared to the front face of the socket block. by meens of S'JE'BWS 2%, or similar sttschi means. The sides of the socket block so. jecent to the recess therein, ere stovicled wit. i'eerweircliy extending slots 25 as shown in Fig; 2; seal Within the socket recess' is located a tilting; block 126, having beveled reei faces 27, as show-s in Y The tilting block is provided, at its sides with outwardly extending tmmniciie edeptecl. to enter the slots 25 yi'rovisee for, and the tiiting block is interacted no operate with the crcoss plate 23, in proviiiing socket for the reception of the file teiig 29. In View of the feet that tengs of file's are ordinarily tapered and of verying size end' shepe, it is necessary to provide suitable means for rigidly cleansing the tang in such 95 position that the file will extend in absolute elinement with the surfece sought to I abraded. Such means ere v provided e pair of clamping thumb screws 30, which ere entered through the plate end iii'e col to clemp the file teng against ti. block on opposite sides ol' 7 3 [03 of sold,

by the angle of the beveled i'e ":lGlfHlIl Weiss vided in its end with an upturned socket head 32, into which head is entered a vertically extending rod 33, which has slidably mounted thereon a forwardly extending bracket arm 34, the rear end of which embraces the vertically extending rod 33 and is adapted to be clamped thereon by means of a set screw 35. The end of the forwardly extending arm has entered thereinto an extensible rod 36, which rod is adapted to .be clamped in adjusted position by means of a thumb screw 37. The rod carries on its forward end a head 38, provided with a vertical slot 39, which is adapted-to receive the upper end of the file blade 40, which latter is clamped within the slot 39 by means of a thumb screw 41 in the head 38.

The upright posts 8 serve as a support for a circular table 42, provided with depending ears 43, through which are entered pivots 44, which serve to pivot the table to the upper endsof the upright posts of the. frame and adapt it to be tilted to different angles. In order to clamp the table in the desired position, a set screw 45 is entered through one of the ears and bears against the up er face of the 0st, so thatwhe-n tightene the table will e clamped and held in suitable position.

The upper and lower guide bars 16 and 17 of the reciprocating frame 14 serve as a mounting for a transversely reciprocating block 46, provided with guide flanges 47, adapted to bear against the rear ed es of the upper and lower guide bars. The block 47, shownin Fig. 4,- has entered therethrough a crank in 48, which issurrounded b a bearing co ar 49 of hardened steel. T e crank pin is provided with a flange 50, which bears against the rear-face of the transversely reciprocating block, and to the rearof the flange the pin is )rovided with screw threads 51 and is entered The screw-threaded end of the crank pin enters a 'l' slot 53,in the front face of a revoluble disk )late 54. The overhanging flanges 55 of t 10 T slot serve as a bearing for thecontact of the clamping washer52,so that when the crank pin is turned in the proper direction the clamping washer will be drawir against the overhanging llanges of the T slot, the flange collar meanwhile overlying the slotted outer face of the revoluhle disk, which arrangement serves to rigidly clanip and hold the crank pin at any suitable )oint with res ect to the center of the revriluble disk. T 1e crank pin is provided, at its outer end, with a recess or slot 56, which permits a suitable tool to be entered thereinto.

The revol'uble disk plate is provided, on its rear face, with a hub socket 57, which receives the forward end of a power shaft 58, which shaft has loosely mounted thereon a cone pulley 59, provided with a hub 60, having in its rear end clutch recesses 61, which are adapted to cooperate with clutch lugs 62 into aclamping washer 52.

on the forward end of a slidabl j 'mounted clutch collar 63, which is keyedor otherwise secured to the shaft 58." The 'clutch collar terminates in a grooved clutch head 64, which is adapted to receive a clutch yoke 65 of'the ,usual'character, mounted upon a slid able rodfitigvhich latter is actuatedfby means of a pivoted handle 67. It will be under stood-that the clutch mechanism can be modified if desired. The shaft is journaled within forward and rear journal bearings 68 and 69, which are secured to a connecting plate 70, which latter rests upon the bedplate of the machine.

In use, when it is desired to insert a file in position, the upper arm 34 is swung to one side of the hole -71 in the center of the table,' which permits a file to be dropped into the socket ail'orde'd therefor within the socket block. The file thus inserted can be adjusted to proper osition by means of the upper and lower tiumb screws, which serve to bring the acting face of the file into exact register with the work, so that as the file isat all points of travel. \Vith the file thus positioned and adjusted, the upper arm 34 can be swung hack into position for the head 38 to receive the upper end of the file, and the'rod 36, being extensible, permits a proper adjustment of the clamping mechanism for the upper end of the file. v

When the file has been pro erly positioned and clamped, the clutch will be thrown to: impart power from the constantly rotating cone pulley wheel to the shaft, which revolves the slotted disk. The revolution of the disk causes the transversely reci rocat ing block to move back and forth Wit in the transverse guideways provided therefor, and likewise causes the vertically reci rocating frame to move up and down, whic i imparts a reciprocating movement to the file. The power transmission mechanism is one which economizes space to a very marked degree,in that the rearwardly extending arm 31, which supports the vertical rod 33, can be located at a position which allows a bare clearance between the arm and the slotted disk wheel, which arrangement.would not be feasible in case a piston rod or similar reciprocating mechanism were employed. The arrangement of the crank pin is one which permits the throw or pitch of the reciprocating n1echanism to be varied to any desired extent; and the power transmission mechanism, as a whole, is one which is smooth and certain in its operation and im )arts a perfect line movement to the tile, w hich thus serves. to ahrade the work evenly during all points of its travel. The clutch mechanism is so cated and arranged that the device will always he under instantaneous control of the operator, which peculiarly its the device fori use as a bench appliance.

reciprocated it will contact the work evenly L ssaesi tang of the file, and m'eans for reciprocating the ciamping'mechanism .as a whole, sub-- stantially as described.
